Developing highly active and durable electrocatalysts for acidic oxygen evolution reaction remains a great challenge due to the sluggish kinetics of the four-electron transfer reaction and severe catalyst dissolution. Recently, Assistant Professor Dr. Kaikai Li, from the School of Materials Science and Engineering (HITSZ), worked with Professor Tong-Yi Zhang (Member of the Chinese Academy of Sciences) reported an electrochemical lithium intercalation method to improve both the activity and stability of RuO2 for acidic oxygen evolution reaction, and revealed the fundamental mechanism behind the strategy. This work, entitled “RuO2 electronic structure and lattice strain dual engineering for enhanced acidic oxygen evolution reaction performance”, was recently published in Nature Communications (Nature Communications 13, Article number: 3784 (2022)). Ms. Yin Qin (a PhD candidate under the supervision of Prof. Tong-Yi Zhang and Dr. Kaikai Li) is the first author and Ms. Tingting Yu is the co-first author. Assistant Professor Dr. Kaikai Li, Prof. Tong-Yi Zhang, Associate Professor Hua-Jun Qiu, and Dr. Xiao-Ye Zhou are the corresponding authors to this work. This work was supported by research grants from the Guangdong Basic and Applied Basic Research Foundation and Shenzhen Science and Technology Program.
